IMPROVEMENT IN FOOT-POWER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, EZRA HUTSON, of Brockport, in the State of New York, have invented certain new and useful Improvements in Foot-Power; and I hereby declare that the following is a' true, full, and exact descripl tion of thc same, reference being had to the accompanying drawings, to the letters of reference marked thereon. In the annexed drawings, which malte a part of this specificationi Figure 1 represents a front elevation of my horse-power.

Figure 2 is a rdtchet on the end of one of the rollers from which motion is derived.

Figure 3 represents the end of a second roller whichco-operates with the rst.

Figure 4 designates la ratchet which may be attached to the end of the second roller.

A represents a vertical frame, to the edges of which are irmly secured the two horizontal arms B. C is a.' shaft which has its hearings .in holes made through arms B.v Upon said shaft the two rollers cZ and e are adjusted. The said rollers are excavated at their inner ends as far out as the line I. The object of the excavation is to receive the fixed ratchet g, and thus admitof the inner ends of rollers d and e coming in contact. m anda represent two pawls designed to act on ratchetg. It will hc seen that the pawls m and n are embedded at one end in the face of the rollers outside of the line I, while the opposite end will rest upon the teeth in ratchet g. On thc upper side of said paws a spring is placed to regulate their pressure on the ratchet g. In

constructing my machine, the ratchet, in place of being attached to shaft C, as seen in fig. 2, may have its teeth cut in the face of either of the rollers d or e, and the pnwls to act on said teeth will he adjusted to the wheel S, as seen in g.,4, the said wheel being fastened to sha-ft C. L designates a pulley placed-near the bottom of frame A. F is a. leather band, the centre o'i' which rests on pulley L, and the ends, after passing under the rollers eZ and e respectively, are brought back over the top of said rollers as far as pulleyL, where they may be fastened to treadles for operating the machine.

In giving motion te the shaft C, which is designed to operate machinery, the treadles fastened to the ends of strap F must alternately'receive the weight of the opcrator, as he bears down first with one foot und then withy the other. `It will he remarked that the band F .will be nailedl to each of the rollers el and e, at unequal .l distances from pulley L, and the end that is furthest from pulley L must he first pressed down with the foot.' i

This will revolve the ro`ller over which the hand passes. The rotation of said roller will communicate a revolving motion to shaft C,`in consequence of the ratchet g being securely fastened to said shaft. The rollers el and e must necessarily revolve with ratchet g alternately, in consequence of their respective pawls catching against the teeth of said ratchet, as the rollers are alternately put in motion by the action of the two hands.

By the operation ahcve described, a continuous rotary motion is imparted io the shaft C. My foot-power can be applied to a great variety of purposes, such ns to drive turning-lathes, propelling hand-Cars, boats, dto.

vHaving thus described my invention, what I claim, and desire to secure by Letters Patent, is- The rollers cl and c, ratchet y, and pawls m and 11., the whole combined substantially as and for the purpose herein set forth.

In testimony that I claim the above, I aihx my signature in presence of two witnesses.

EZR'A HUTSON. Witnesses:
